Lonesome Dove, Volume 2: Comanche Moon by Larry McMurtry

MAGGIE CONSIDERED IT a happy turnabout that she now had a position in the store that had once been the Forsythes'. She did the very jobs that Clara had once done: unpacking, arranging goods on the shelves, helping customers, writing up bills, wrapping the purchases that required wrapping. She thought often of Clara, and felt lucky to have, at last, a respectable job. Clara, she thought, would have understood and approved. The store's new owner, Mr. Sam Stewart, was from Ohio, and a newcomer to Austin. He knew little of Maggie's past, and what he knew he ignored. Fetching and competent clerks were not plentiful in Austin-Mrs. Sam Stewart was glad to accept the fiction that Maggie was a widow, and Newt the son of a Mr. Dobbs, killed by Indians while on a trip. Sam Stewart had a few irregularities in his past himself and was not disposed either to look too closely or to judge too harshly when Maggie applied for the job, though he did once mention to his formidable wife, Amanda Stewart, that Maggie's boy, Newt, then four, bore a strong resemblance to Captain Call.

"I'd mind your own business, if I were you, Sam," Amanda informed him. "I'm sure Maggie's done the best she could. I'll nail your skin to the back door if you let Maggie go."
